What is "chaber"

Chaber or Ḥaber is a Biblical term meaning "associate"; "colleague"; "fellow"; "companion"; "friend" ( Ps. ).

The term is ordinarily used in rabbinical lore in its original Biblical sense ( Abot ii. 9, 10). A Talmudic proverb says, "Thy chaber has a chaber, and thy chaber's chaber has a chaber; thy words will thus circulate and become public" ( Baba Batra 38b; 'Arakin 16a).
